Opening new frontiers, ISRO is developing a unique Reusable Launch Vehicle to put satellites into orbit and substantially reduce costs.

Built at the Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram, ISRO has completed the structural design and fabrication process studies for a technology demonstrator flight which is likely to take place in a couple of years.

"Conceptual design of the auxiliary power system for reusable launch vehicle and initiation of studies for the development of 2,000 kN thrust semi-cryogenic engine have been undertaken as part of developments related to technologies for reusable launch vehicles," according to the Annual Report (2005-06) of the Department of Space (DoS).

The aerodynamic and baseline characterisation, reference trajectory for the mission, avionics configuration, structural design and fabrication process studies have also been completed, the report said.

The Performance Budget of the DoS stated that the Preliminary Design Review of mechanical integration, electrical integration and checkout system would be completed in the 2006-07 fiscal.

The first stage of the RLV is configured as a winged body system, which will attain an altitude of around 100 km and deliver nearly half the orbital velocity.

After burnout, the vehicle will re-enter the Earth's atmosphere and will be made to land horizontally on a runway, like an aircraft.

In the second stage, after delivering the payload, the vehicle will be made to re-enter the atmosphere and will be recovered using airbags either in sea or land.
